  • 2. Why Behaviourism? • Psychology is a science of behaviour • It must use objective methods • It can use animals or human participants • It discards consciousness and instead the focus is on stimulus-response links • It should ultimately predict and control behaviour • If humans are just another species, we should be able to study them the same way.

    3 Theories of B.F. SkinnerBEHAVIORISMBehaviorism, or behavior learning, is one of the most influential theories of the last half century.This theory states that learning is a change in behavior that is controlled by the consequences, either positive or negative, that follow the behavior.

    4 Reinforcers are consequences that increase or strengthen behaviors.
